Visual-kei is a movement born in the early 80's in Japan, it's about music and image at the same time. Visual-kei band members use makeup and dress up in a very eccentric way. Members of these bands make a dramatization of their music on stage and their image helps them on it. Individualism is what Visual-kei people look for, not to be part of society so to speak.
The dramatization of their music is an influence of Kabuki theatre.
Their music is a bit difficult to classify, but most of Visual-kei bands follow a pattern to make music, although nowadays their music has been very influenced by western music. If someone wants to know how Visual-kei sounds like, go to bands like: Baiser, Pierrot, Dir en grey (Visual-kei times), Noir Fleurir, Aliene Ma'riage, Lareine, Vidoll, etc.
Visual-kei is not gothic as some people think since Visual-kei bands with gothic influence began to appear in the 90's and Visual-kei already existed before it.
